How can beryllium exposure occur?
Beryllium exposure varies among different segments of the population. The general population is exposed to normally low levels of beryllium in air, food, and water. People working in industries where beryllium is mined, processed, machined, or converted into metal, alloys, and other chemicals, may be exposed to high levels of beryllium. People living near these industries or near uncontrolled hazardous waste sites may also be exposed to higher than normal levels of beryllium.
